New accessories for H-alpha solar observation / imaging

Our sun is a fascinating target even when the solar activity is low - given that the telescope aperture can be increased sufficiently. When equipped with a heated SolarSpectrum H-alpha filter, telescopes from 80mm aperture to 280 mm aperture will show incredibly faint, rapidly changing structures. A SolarSpectrum filter with matching D-ERF-filter and telecentric beam accessories will turn almost every telescope into a highest resolution H-α-telescope. These heated H-alpha filters are manufactured for observatories and ambitious amateurs who want to utilize the aperture and resolution of their existing large telescopes for detailed imaging and monitoring faintest solar features, instead of just taking a quick look at our closest star with a comparably small objective aperture.

SolarSpectrum filters have no central obstruction and the whole H-alpha stack of optical elements inside is precision heated with a autocorrecting thermo-controller. There is no need for frequent manual or visual calibration or readjustment of the H-alpha line during the course of a day. Hence SolarSpectrum filters are the brand of choice for long term solar observation, time-lapse photography or public observation - were a large crowd of people must be served quickly without constant realigning of the H-alpha image.

The thermal calibration range is wide enough to shift the observed center wavelength – to observe in the red or blue wing of the H-alpha-line. SolarSpectrum filters are for those who prefer quality over price. They are available in different HBWs (band-widths). This influences solar surface contrast as shown in the photographs to the right.

Solar Spectrum Research-Grade filters are selected to deliver a very homogenous image across the complete field of view. The new series of SunDancer filters in addition allow for manual fine tuning to widen H-alpha wing observation.

Be warned: this intriguing combo of fast-changing protuberances, filaments, flares and surges rising up from the sun´s surface can cause you to become addicted to solar-observing!

Our company exists now for more than 50 years. In this time, more than 15.000 Baader Planetariums (the first patented product of our company) help all over the world to give students an understanding of astronomical correlations. In our own manufactory, more than 500 observatory domes have been produced and delivered turnkey-ready. Instruments and telescope accessories from "Baader" are known for their high qualities by many astronomers and universities. We consider it our duty and obligation, not only to sell telescopes, but an indivdually selected telescope system, that brings you a lifetime of joy.
